4.8.3 Parallelization Directives

A parallelization directive is a special comment that directs the compiler to attempt to parallelize the next DO loop. These are summarized in Appendix D and described in the chapter on parallelization in the Fortran Programming Guide. Both Sun and Cray style parallelization directives are now deprecated as obsolete., The OpenMP Fortran API directives and parallelization model is preferred. OpenMP parallelization is described in the OpenMP API User’s Guide.
